Ruby on Rails 教程测试 10..20

Question

有人可以通过 Michael Harty 的 10.20 Ruby on Rails 教程测试吗？ 我有以下我无法理解的错误；除了我完全按照教程的说明进行操作。

例如。教程说要改成 noreply@example.com"] 但它指向这条线的错误...... 我是否应该更改此行并通知 Michael Harty 有关错误/做其他事情来修复错误？

我使用：ruby-2.3.0 rails - 4.2.2

错误：

我添加了将 Michael 更改为 Tatyana 的文件，但仍然出现 1 个错误，如下所示：我找到此文件并将其添加，将 michael 更改为 tatyana，但仍然出现如下错误： 错误[“test_account_activation”，UserMailerTest，2016-03-23 16:43:44 +0000] test_account_activation#UserMailerTest (1458751424.20s) ActionView::Template::Error: ActionView::Template::Error: 缺少要链接的主机！请提供 :host 参数，设置 default_url_options[:host]，或设置 :only_path 为 true app/views/user_mailer/account_activation.html.erb:9:in _app_views_user_mailer_account_activation_html_erb__2380038393264600902_67365800' app/mailers/user_mailer.rb:5:inaccount_activation' test/mailers/user_mailer_test.rb:9:in block in <class:UserMailerTest>' app/views/user_mailer/account_activation.html.erb:9:in_app_views_user_mailer_account_activation_html_erb__2380038393264600902_67365800' app/mailers/user_mailer.rb:5:in account_activation' test/mailers/user_mailer_test.rb:9:inblock in '

Answer 1

该错误来自user_mailer_test.rb:6 第 6 行。

在 class UserMailer 第 3 行中，您将 user 对象传递给 def account_activation(user) ，但在您的 UserMailer.account_activation 中没有传递任何内容。继续关注那本书，它应该是这样的例子。

user = users(:michael)
user.activation_token = User.new_token
mail = UserMailer.account_activation(user) # right here user passed.

Answer 2

test/mailers/user_mailer_test.rb 如下允许摆脱一个错误：

需要'test_helper'

类 UserMailerTest

测试“account_activation”做

user = users(:tatyana)

user.activation_token = User.new_token

mail = UserMailer.account_activation(user)

assert_equal "Account activation", mail.subject

assert_equal [user.email], mail.to

assert_equal ["noreply@example.com"], mail.from

assert_match user.name,               mail.body.encoded

assert_match user.activation_token,   mail.body.encoded

assert_match CGI::escape(user.email), mail.body.encoded

结束

结束

还有一个如下： 错误[“test_account_activation”，UserMailerTest，2016-03-23 16:43:47 +0000] test_account_activation#UserMailerTest (1458751427.01s) ActionView::Template::Error: ActionView::Template::Error: 缺少要链接的主机！请提供 :host 参数，设置 default_url_options[:host]，或设置 :only_path 为 true app/views/user_mailer/account_activation.html.erb:9:in _app_views_user_mailer_account_activation_html_erb__1635017718511086794_82209820' app/mailers/user_mailer.rb:5:inaccount_activation' test/mailers/user_mailer_test.rb:9:in block in <class:UserMailerTest>' app/views/user_mailer/account_activation.html.erb:9:in_app_views_user_mailer_account_activation_html_erb__1635017718511086794_82209820' app/mailers/user_mailer.rb:5:in account_activation' test/mailers/user_mailer_test.rb:9:inblock in '

Answer 3

UserMailer.account_activation方法需要user参数在测试中。

class UserMailerTest < ActionMailer::TestCase

  test "account_activation" do
    mail = UserMailer.account_activation(User.create(email: "foo@bar.com"))
    assert_equal "Account activation", mail.subject
    assert_equal ["to@example.org"], mail.to
    assert_equal ["from@example.com"], mail.from
    assert_match "Hi", mail.body.encoded
  end
end
